IMPROVEMENT IN MOLDS FOR CASTING WHEELS.

Specification forming part of Letters Patent No. 149,383, dated April 7,1874; application filed November 5, 1873.

To all whom it may concern:

Be it known that 1, Jules EV'ERINGHAM, of Cleveland, in the county ofGuyahoga and State of Ohio, have invented a certain new and ImprovedMold for Casting Childs Carriage- NVheels, of which the following is afull and complete description, reference being had to the accompanyingdrawings, making part of the same.

The nature of my improvement consists in apeculiarly-constructed moldfor casting carriagewheels, which is made up in sections with referenceto-its being taken to pieces to remove the hub or wheel.

Figure 1 is a side view of the mold. Fig. 2 is a top view. Fig. 3 showsthe sections of the mold. Fig. 4 is a transverse section of the mold inthe direction of the line a 00, Fig. 2. Figs. 5 and 6 are elevations ofthe wheel.

The mold consists of a series of sections or leaves, as seen at A B CDE, Fig. 1. In the top plate or section are two holes, a and b, as seenin Figs. 2 and 3, a being the gate, and b the vent. The parts orsections of the mold are secured together by means of a bolt passingthrough the ends, as seen at F G, Fig. 4, with screw-nuts thereon. Theplates B O D are divided into two sections through their centers, asindicated by the dotted lines 0, Fig. 2. These sections are seen, at Aand B, moved out from the mold. The object of dividing the sections willhereinafter be explained.

In making the wheel, the top plate or cap A is removed, and the thimbleis first placed in the mold, with the largest end over the core H, andthen the spokes are passed through the holes or openings I in the platesof the mold, one-half of the diameter of each hole being in therespective plates or sections through which they pass, as these holes oropenings are on the radius of a circle, as indicated in Fig. 3,corresponding with the position of the spokes seen in Figs. 5 and 6.After the thimbles and spokes are placed in the mold, the top plate A isthen put on, so that the core J will enter the bore of the thimble atthe small end. The two cores, being arranged in line with each other,will be also in line with the bore of the thimble. After the top plate Acovers the mold, the sections are all tightly fastened together by meansof the nuts at the ends of the bolts. The liquid metal is then pouredinto the mold through the gate or hole a, which completely surrounds thepipe or thimble, and flows in and around the ends of the spokesprojecting into the mold. The contact faces or joints of the sectionsare sufficiently close to prevent the molten metal from passin gin orbetween them. When the metal is cold, the nuts are turm d to loosen thesections-0f the mold to take out the hub, Which is done by movinglaterally the double sections B O D,'as seen in Fig. 3, which Withdrawsthese sections from between the double rows of spokes-that is, from thecentral part of thehub at d, Fig. 6-the ends 0 outside of the spokesbeing molded in the outside plates A and E. Thus, by-removing'thecentral sections, the hub is readily taken out of the mold complete.

By reference to Fig. 4, it will be seen that the enlarged ends of thehub, which received the spokes, are formed in the two outside sections,or A B and D E, and the spokes I in the joints. (Seen in the drawings.)

The metal of the hub shrinks tightly around the pipe or thimble andspokes, thus securely uniting the spokes, hub, and thimble together.

What I claim as my invention, and desire to secure by Letters Patent, is

The mold, consisting of a series of plates or sections, having cores H Jand spoke-holes I, arrranged substantially as described, and for thepurpose set forth.
